What's it mean when Clover hangs at "root device uuid is..."?

I have a working Yosemite system using Chimera. I just upgraded my BIOS to UEFI, and I'm trying to get Clover working. This is all I did:

- Installed Clover from http://sourceforge.net/projects/cloverefiboot/
- Got config.plist-Standard.zip from http://www.tonymacx86.com/yosemite-desktop-guides/144426-how-install-os-x-yosemite-using-clover.html (because I have an AMD Radeon HD 6570)
- Changed "Boot" -> "DefaultVolume" to "Macintosh" (the name of my HD)
- Changed "Boot" -> "Arguments" to "-gux_defer_usb2 -gux_no_idle kext-dev-mode=1" (from my working /Extra/org.chameleon.Boot.plist)

I haven't copied any kexts out of SLE because http://www.tonymacx86.com/yosemite-desktop-guides/144426-how-install-os-x-yosemite-using-clover.html says they should still work in SLE, and that I can have Chimera and Clover both installed because I'm using UEFI.

When I boot into Clover and select "Boot Mac OS X from Macintosh", the screen clears and nothing else happens. If I set -v as a boot flag, I see some text:

efiboot loaded from device: (and a long path)
boot file path: System\Library\CoreServices\boot.efi
......................
root device uuid is... (and a uuid)
++++++++++++++++++++++++++++++++++++++++ (long row of plusses - I didn't count how many)

I know I'm missing something, but what? What's supposed to be happening at this point?

Do I need to install any of the Drivers64UEFI from the Clover installer, such as either OsxAptioFixDrv-64 or OsxAptioFix2Drv-64?

I installed OsxAptioFixDrv-64, and I also copied the Clover settings from http://www.tonymacx86.com/yosemite-...emite-gigabyte-ga-z68mx-ud2h-b3-progress.html, and now I can boot with Clover into Mac OS. I don't know which of these two things fixed it for me, and I haven't tested thoroughly yet, but things seem to work!

You could probably do away with some of those DSDT fixes in the Clover settings, but its working now, so thats most important.

Just curious - which ones caught your eye? Is there a list of what they all do?
